Abstract
Recently, with the greatly growth of multimedia and wireless communications, high data rate is required for the increasing data transmission of information. Considering the dielectric properties and losses, the demand for low dielectric constant (Dk) and low dissipation factor (Df, or loss tangent) material is urgent as the data rate and operating frequency increase. In this study, we used the low Df Corning® Willow® Glass as the substrate. By means of designing the dipole antenna and Yagi-Uda antenna on the glass, the glass has been demonstrated both in simulation and experiment for antenna application. All experiments were conducted by the gravure offset printing (GOP) method. In the latter half of this study, in order to have better transparency, the linewidth of the metal line is shrank to 3 μm and the space is extended in a range of 200~300 μm. In addition, when we fix the space and adjust the metal lines, the center frequency will shift to lower frequency as the metal lines becoming thinner. The reason why the center frequency shifts to lower frequency is that when the fill factor is smaller, the electric field prefers to enter into the substrate than the air, that is, the effective refraction index increases.
